Snowboard edge tuner

ABSTRACT

A snowboard edge tuner, having a fixed plate, an angling plate, and a file; one side of a bottom surface of the fixed plate is provided with a file mounting seat in which the file is mounted; at least one mounting hole is vertically formed on a side of the fixed plate away from the file mounting seat; the angling plate is movably mounted up and down in said at least one mounting hole; the angling plate has at least one abutting part extending out of the at least one mounting hole.

BACKGROUND OF THE INVENTION

The present invention relates to the technical field of snowboard edge repairing, in particular to a snowboard edge tuner.

After a period of use, the base edge of the snowboard frequently contacts with a snow surface, leading to a plurality of scratches which result in a certain degree of abrasion. The turning or braking performance of the snowboard during use is therefore affected. In view of this, the base edge needs to be periodically polished and repaired. If the snowboard is not used for a long time, the base edge will be rusted, and so the base edge of the snowboard also needs to be repaired.

Many edge repairing tools are available in the market, for example, different calibration rulers of different specifications are used for inserting a file, so that different angles between the file and the base edge of a snowboard can be formed for polishing purpose. However, different calibration rulers are required for different polishing angles, so replacement of different calibration rulers results in complicated use.

Currently, an edge tuner with an adjustable base edge angle ruler has been developed. As shown in FIG. 1 , by laterally adjusting the position of a sliding block 3′, a polishing angle α′ in a range of 0.5 degree to 2 degrees between the base edge angle ruler 1′ and the file 2′ can be realized; when the sliding block 3′ abuts against the snowboard 4′, a certain angle is formed between the file 2′ and the base edge 5′ of the snowboard 4′ to polish and repair the base edge 5′ of the snowboard 4′. However, according to the edge tuner of the structure, as shown in FIG. 2 , when adjusting the angle, the fixing screw 6′ has to be first loosened before the sliding block 3′ can slide laterally back and forth. Since the sliding block 3′ changes its position due to lateral sliding, user may feel unfamiliar to hold the edge tuner to move it back and forth for polishing with the sliding block 3′ changed in its position, thereby affecting the subsequent polishing effect. Further, because sliding of the sliding block 3′ is difficult to control in that user may easily slide the sliding block 3′ more than necessary, adjustment of the sliding block 3′ is therefore inconvenient. Besides, repeated use of the edge tuner for polishing can cause abrasion to the part where the bottom of the sliding block 3′ abuts against the snowboard 4′, and such abrasion can affect a polishing angle between the edge tuner and the base edge, and thus resulting in errors in subsequent maintenance, polishing and repairing.

DETAILED DESCRIPTION OF THE INVENTION

As shown in FIGS. 3 to 9 , the snowboard edge tuner 10 of the present invention comprises a fixed plate 1 and an angling plate 2.

One side of a bottom surface of the fixed plate 1 is provided with a file mounting seat 11, a lateral mounting groove 111 is formed in the file mounting seat 11; a file 3 is mounted in the mounting groove 111; a vertical retaining wall 12 is formed between the file mounting seat 11 and another side of the bottom surface of the fixed plate 1; the file 3 passes through the mounting groove 111 and extend to be positioned above the retaining wall 12 and below said another side of the bottom surface of the fixed plate 1.

Vertical mounting holes 13 are formed on a side of the fixed plate 1 away from the file mounting seat 11, the angling plate 2 is movably mounted in the mounting holes 13; the angling plate 2 is movable up and down in the mounting holes 13; the angling plate 2 comprises abutting parts 21 extending out of the mounting holes 13 respectively. By adjusting lengths of the abutting parts 21 extending out of the mounting holes 13, i.e. adjusting the lengths of the abutting parts 21 extending out of the bottom surface of the fixed plate 1, an angle between the a front surface 203 of snowboard 20 and the file mounting seat 11 as well as the file 3 (when being fixed) can be controlled.

Specifically, as shown in FIGS. 5 and 6 , when the snowboard edge tuner 10 is used to polish a base edge 201 of the snowboard 20, the retaining wall 12 of the fixed plate 1 abuts against a side edge 202 of the snowboard 20, and the abutting parts 21 of the angling plate 2 abut against and are substantially parallel to the front surface 203 of the snowboard 20, so that the file 3 extending outwardly from above the retaining wall 12 can abut against the base edge 201 of the snowboard 20 and form a certain angle α with the base edge 201, and then the file 3 can be driven to polish the base edge 201 by moving the fixed plate 1.

By adjusting the lengths of the abutting parts 21 extending out of the mounting holes 13, a distance between a portion of the fixed plate 1 corresponding to where the angling plate 2 is positioned and the snowboard 20 can be adjusted. In other words, different angles α can be formed between the file 3 and the base edge 201, so as to meet the requirements of polishing and repairing the base edge 201 at different angles.

With reference to FIG. 10 and FIG. 11 , the lengths of the abutting parts 21 extending out of the bottom surface of the fixed plate 1 are adjusted compared with FIG. 5 and FIG. 6 , such that when the abutting parts 21 of the angling plate 2 abut against the front surface 203 of the snowboard 20 and are substantially parallel to the front surface 203 of the snowboard 20, a different angle α can be achieved compared with FIG. 5 and FIG. 6 .

Therefore, as the angling plate 2 is movably mounted on the fixed plate 1, and the angling plate 2 is movable up and down with respect to the fixed plate 1, when adjusting the polishing angle, a positional relationship between the angling plate 2 and the fixed plate 1 will not be changed greatly. This ensures that user is still familiar with holding and using the snowboard edge tuner 10 during polishing even after a change in positional relationship between the angling plate 2 and the fixed plate 1, thereby guaranteeing a good polishing effect for ordinary users when polishing the snowboard 20.

As shown in FIG. 6 , a bottom surface of the side of the fixed plate 1 away from the file mounting seat 11 is provided with a protection protruding part 14 protruding downward; a bottom surface of the protection protruding part 14 extend beyond or is flush with a bottom surface of the file 3, in other words, the bottom surface of the protection protruding part 14 is at the same level (FIG. 6 ) as the bottom surface of the file 3 or extending further downwardly (FIG. 11 ) as compared with the bottom surface of the file 3, so as to conceal the file 3; a polishing area 15 is formed between the protection protruding part 14 and the retaining wall 12; a width of the polishing area 15 is substantially equal to a width of the base edge 201 of the snowboard 20; the bottom surface of the file 3 is exposed in the polishing area 15 to ensure that the base edge 201 can be polished, and the protection protruding part 14 abuts against the front surface 203 of the snowboard 20 to prevent the front surface 203 of the snowboard 20 from being abraded by the file 3.

As shown in FIG. 4 , a guide post 16 is provided on each of two sides of the retaining wall 12, and the guide post 16 can abut against the side edge 202 of the snowboard 20 to assist sliding of the snowboard edge tuner during polishing.

As shown in FIG. 7 , a screw hole 17 communicating with the mounting groove 111 of the file 3 is formed on the fixed plate 1, and a file adjusting screw 31 is fastened into the screw hole 17 and abuttable against the file 3 so that the file 3 can be adjusted and replaced.

As shown in FIGS. 7 to 9 , the angling plate 2 comprises an adjusting plate 22 horizontally disposed, and the abutting parts 21 vertically extending downward from two sides of the adjusting plate 22 respectively; the two abutting parts 21 extend into the two mounting holes 13 of the fixed plate 1 respectively; alternatively, only one abutting part 21 can be disposed at either one of two sides of the angling plate 2.

The angling plate 2 is movably mounted up and down in the mounting holes 13 of the fixed plate 1 via an adjusting device 4; the adjusting device 4 comprises an adjusting shaft 41, an adjusting knob 42 and an adjusting spring 43; the adjusting shaft 41 penetrates through the fixed plate 1 from the bottom surface of the fixed plate 1 and sequentially passes through the adjusting spring 43 and a middle through hole 221 of the adjusting plate 22 and then being threaded with the adjusting knob 42; in other words, the adjusting knob 42 is threaded with an outer top end of the adjusting shaft 41 and also abuts against a top surface of the adjusting plate 22; the adjusting spring 43 is arranged between a bottom surface of the adjusting plate 22 and a top surface of the fixed plate 1 so that two ends of the adjusting spring 43 abut the bottom surface of the adjusting plate 22 and the top surface of the fixed plate 1 respectively; the adjusting plate 22 is movable up and down on the adjusting shaft 41 via the middle through hole 221; the adjusting knob 42 rotates to drive the adjusting plate 22 to move downwardly, and resilience force of the adjusting spring 43 biases the adjusting plate 22 to move upwardly.

External threads are formed on an outer surface of the adjusting shaft 41; a connecting hole 421 is formed on a bottom surface of the adjusting knob 42; a connecting sleeve 422 is fitted in the connecting hole 421, and internal threads corresponding to the external threads of the adjusting shaft 41 are formed in the connecting sleeve 422.

By rotating the adjusting knob 42 clockwise, in other words, by driving the adjusting knob 42 into the adjusting shaft 41, the adjusting knob 42 moves vertically downward to press the adjusting plate 22 to move downwardly towards the fixed plate 1, thereby compressing the adjusting spring 43 and driving the abutting parts 21 on the adjusting plate 22 to extend out of the mounting holes 13; by rotating the adjusting knob 42 counterclockwise, in other words, by driving the adjusting knob 42 along a direction out of the adjusting shaft 41, the adjusting knob 42 moves vertically upward to be away from the fixed plate 1, and the adjusting plate 22 will also move upwardly together with the adjusting knob 42 due to the upwardly biased resilience force of the adjusting spring 43, thereby driving the abutting parts 21 to move upwardly in the mounting holes 13.

Therefore, by simply rotating the adjusting knob 42 clockwise and counterclockwise, the angling plate 2 can be conveniently moved up and down, and the lengths of the abutting parts 21 extending out of the mounting holes 13 can be adjusted.

The adjusting shaft 41 can be a rod part of a bolt; the bolt penetrates the fixed plate 1 from the bottom surface of the fixed plate 1 through the top surface of the fixed plate 1; a fixing nut 44 is provided on the top surface of the fixed plate 1 to lock the bolt on the fixed plate 1, thereby ensuring that the rod part of the bolt extending out of the top surface of the fixed plate 1 remains fixed in length, in other words, ensuring a fixed length of the adjusting shaft 41. By providing the adjusting shaft 41 as a part of the bolt, the production and installation of the product are facilitated.

Further, the snowboard edge tuner 10 is further provided with a scale device 5, the scale device 5 comprises an annular ring of scale markings 51 which is annularly disposed on a top surface of the adjusting plate 22 around the adjusting knob 42, and an indicator 52 which is provided on the adjusting knob 42; a range of scale of the scale markings 51 can be from 0.5 degree to 2 degrees, a distance between every two adjacent scale markings 51 corresponds to a thread pitch between the adjusting knob 42 and the adjusting shaft 41. Therefore, when the indicator 52 of the adjusting knob 42 rotates by a certain angle to a scale marking, the abutting parts 21 of the angling plate 2 is controlled to extend out of the mounting holes 13 of the fixed plate 1 by a distance corresponding to the angle which the indicator has rotated.

The scale device 5 further comprises a limiting protruding part 53; the limiting protruding part 53 is provided on the top surface of the adjusting plate 22 and positioned adjacent to a periphery of the adjusting knob 42; the indicator 52 is a protruding part protruding from the periphery of the adjusting knob 42; when the adjusting knob 42 rotates, the indicator 52 can abut against two ends of the limiting protruding part 53 at two end rotating positions (a starting point position and an end point position) of the adjusting knob 42 respectively (see FIG. 5 and FIG. 12 respectively), so that the adjusting knob 42 is prevented from excessive rotation which may cause adjustment errors or disengagement of the adjusting knob 42 from the adjusting shaft 41.

Furthermore, a positioning device 6 can be further provided between the adjusting knob 42 and the adjusting plate 22; the positioning device 6 comprises an annular positioning groove 61 formed on the top surface of the adjusting plate 22, and a spring-loaded pin 62 provided on the bottom surface of the adjusting knob 42; the spring-loaded pin 62 is provided in a pin hole 423 on one side of the connecting hole 421 in the bottom surface of the adjusting knob 42, and is spring-biased to extend and abut against the annular positioning groove 61; the annular positioning groove 61 is located on an inner side of the annular ring of scale markings 51; the annular positioning groove 61 is provided with a plurality of indenting parts 611, and each indenting part 611 corresponds to a corresponding scale marking. Therefore, when the adjusting knob 42 is rotated, the spring-loaded pin 62 can be driven to move on the indenting parts 611, so as to provide certain elastic feedback through the spring-loaded pin 62, and thus sharpening the user's sense of rotation while rotating the adjusting knob 42; further, the spring-loaded pin 62 can accurately position the indicator 52 by fitting into a corresponding indenting part 611, thus ensuring the accuracy of adjustments.

In summary, according to the snowboard edge tuner 10 of the present invention, the angling plate 2 is movably mounted on the fixed plate 1 and is movable up and down with respect to the fixed plate 1; by moving the angling plate 2 up and down, the angle of the file 3 during polishing can be adjusted, thereby ensuring the using experience without greatly changing the structural arrangements of the components of the snowboard edge tuner 10 in case of angle adjustments. Besides, by arranging the adjusting knob 42 of the adjusting device 4, the vertical movements of the angling plate 2 is achievable via convenient, rapid and precise rotation of the adjusting knob, making the adjustment simpler and faster.

If, after a long period of use, abrasion occurs at bottom ends of the abutting parts 21 of the angling plate 2 where the abutting parts abut against the snowboard, resulting in the lengths of the abutting parts 21 of the angling plate 2 extending out of the mounting holes 31 shorter than intended, scale markings for rotation of the adjusting knob 42 are not required to be adjusted accordingly; instead, user may simply thread the adjusting knob 42 further into the adjusting shaft 41 to compensate for the abrasion, thereby calibrating the lengths of the abutting parts 21 of the angling plate 2 extending out of the mounting hole 31 to the intended lengths. In other words, with reference to FIG. 9 , more of the internal threads of the adjusting knob 42 are threaded with the external threads of the adjusting shaft 41, so that the angling plate 2 is further driven to move downwardly, thereby ensuring that the lengths of the abutting parts 21 extending out of the mounting holes 31 to abut against the snowboard 20 remain the same as the intended lengths before abrasion occurs. This guarantees the accuracy of the polishing angle of the edge tuner and ensures precision in the polishing of the base edge of the snowboard.
